Question

Headphones that originally cost $80 were marked up to $92. By what
percentage were the headphones marked up?

Answer 1

Answer:

15%

Step-by-step explanation:

We can set up an equation to find out what percentage will equal $92.

That would be:

80x = 92

Now, you just solve for x.

$80x = 92\\x = \frac{92}{80} \\x = 1.15$

Now since the question at what percentage did the headphones go up, the answer would be by 15%
